<OT> Another postscript question:SOLVED

[Joel Hammer]

Well, I messed around and found the solution.
At the end of the EPS file, there is a command _R
like this:

_R
S
%%Trailer
cleartomark
countdictstack exch sub { end } repeat
restore
%%EOF

S stands for showpage
_R is defined as below:
/_R {   % restore from saved state
   _s restore
} def

Removing _R makes things works just as expected.  When I figure out what
_s is, I may have more of a clue as to what is going on.

What really bugs me is that ps2epsi has this apparent bug, at least when
working with enscript. Oh well, it works when you take you the _R out.
